[android-beginners] Re: findViewById() function return null
What is timestamp of this xml file? How does it work with the app?
I think the reason it was suggested was to convince the thing to
recompile. I don't think that's the problem. I'd guess you are using
the m5 sdk, but the layout file you posted is m3. try changing the
id=@+id... to android:id=@+id...

However, the application crushed. After I debug into the app, I found
that the edit was null.
It would appear that your res/layout/relative_view.xml file does not
have a view with the id of @+id/entry. I would have expected a
compiler error, though, complaining that R.id.entry was not found.
Perhaps your R.java file is out of sync with the contents of your res/
directory tree.
Try updating the timestamp on your res/layout/relative_view.xml file
(e.g., touch res/layout/relative_view.xml in Linux) and recompile. Or,
update res/layout/relative_view.xml to include an EditText element with
an android:id of @+id/entry, since it would appear it doesn't have one
already.

[android-beginners] Re: HELP! R.layout.main cannot be resolved error
Well, the resource stuff isn't a Java thing, it's an Android thing.
Basically if you put a layout xml file in res/layout, you reference it
by filename when you call setContentView. For instance, if you have
res/layout/my_fancy_layout.xml, you make a call to
setContentView(R.layout.my_fancy_layout).
But, it sounds like you have a main.xml in that directory and using it
correctly with setContentView. The layout xml looks valid for the m5
sdk. Are you using m5 or m3? Also, if you are using eclipse, it should
tell you if theres a problem in the xml file itself when you open the
file. That might give some insight.

Hi,
It seems that res filename must contain only [a-z0-9_-.]. (It is

Change your layout filename from DroidDraw.xml to droiddraw.xml or
simply main.xml, and hand same name to setContentView().

[android-beginners] Re: EditText getText() to string for notification
Because message is whatever text is in the EditText whenever this
bit of code runs. I assume this is ran in onCreate? Probably this is
blank unless you gave it a default value. What you might try is to
remove the message variable and then call text.getText().toString() in
the Toast.makeText method.

I haven't worked with aidl, but just looking at the docs gives me a

through the ServerConnection callback you get one or more interfaces

how would you declare an interface in the AndroidManifex.xml ?

[android-beginners] Re: Please Help on Example / Tutorial by Reto Meier
It looks like his example has the user actually typing in some coordinate data to the notes field for a contact. It'd be hard to give you sample code in that case. It really depends on what they have written in the notes. It could be the recipe for bushs baked beans for all you know, but let's assume you tell the user to input in the form: latitude,longitude. All you'd do is read the notes and then coords.split(,); along with casting those values to a number of some sort. From there, I'd guess loc is just a Location built with that coords data.

[android-beginners] Re: openFileOutput questions / clarifications
1. Should be /data/data/com.organization.android.app.myapplication/ files/test.txt 2. I think it is possible to use normal file i/o code (by normal, I mean not using openFileOutput) to do this. 3. There isn't anything stopping another app from reading it. 4. I found this: http://blogs.sun.com/manveen/entry/blob_vs_file_system_storage which might give you an idea, although I don't really agree with all of it. For example: # The whole point of storing data in a SQL database, is to put some kind of ordering and structure on your data, as well as being able to search on these data. But how do you search in the # binary data of a picture? That's what other columns in the table are for. Just because a column is there doesn't mean you need to search with it.

I think you should use relative addressing. As I recall, the files location for your application is not set in stone. It may change. A content provider is a way to give access to your data from other applications or let your data access other applications data. I suppose since the MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE flags lets another app access your file, you wouldn't have to use a content provider, but I suppose it would be discouraged to do it this way. I'm not sure if there is an easy way to change the flag. I haven't seen one. I don't think I'd manipulate the file data. I think maybe just opening the file for output with a different flag would do it. Either that or maybe you'd have to get the file contents, then delete and re-create it with the new flag.

Or should I use relative addressing? 3. There isn't anything stopping another app from reading it. So the content provider is just a convenient way to access data from our application? Also, I have not noticed a function to change the mode of an existing file. Is there a way to change the mode? Or do I have to actually manipulate bytes in the file to do that?

I found this:http://blogs.sun.com/manveen/entry/blob_vs_file_system_storage which might give you an idea, although I don't really agree with all of it. For example: # The whole point of storing data in a SQL database, is to put some kind of ordering and structure on your data, as well as being able to search on these data. But how do you search in the # binary data of a picture? That's what other columns in the table are for. Just because a column is there doesn't mean you need to search with it.

Or is there another way to specify where i want my files? 3) If i set the file mode to MODE_WORLD_READABLE, what is stopping an outside application from using the path to read it? 4) sqlite3 supports byte data types (called blob) but the contentprovider tutotial recommends that we store a string that represents the path of the file instead, why is that?

[android-beginners] Re: problrm in calling activity/plz do solve his problem i am running out of time...
It looks like you are asking 3 questions. My answers... 1. I don't understand why you need to call one activity from your others. 2. You could add a logo either by adding a imageview to every layout, or you could extend a layout class that has an imageview in it, then just specify that layout view in your layout xml (instaed of whatever your top level container view is). 3. I think you might want to look at Gallery.

[android-beginners] Re: best way to setup 3 buttons
Yes, that's expected behavior for fill_parent. It fills what's left in the parent which means it pushes other things out of view.

I don't think there's much you can do. You will have to allow for a long boot time or upgrade your hardware.

I do that routinely when benchmarking emulator binaries on different PCs. now, the very first time you launch the emulator on a clean PC, the boot sequence will be longer because the system will build various caches. any boot after than should be faster. the Application not responding dialog you see is just a symptom of having a very long boot sequence (at the moment, the Application Manager is not too sharp and considers that the Home application is not responding because the CPU was taken by other processes during the long boot sequence). now, why the boot sequence is long on your machine can be from two things: - you're running on a low-end CPU (by today's standards of course, i.e. anything 2 real GHz or with 1MB L1 cache would qualify) - there are probably some bad dependency / race conditions in our boot sequence that make the system_server crash in a loop during the boot on some machines. it's unfortunately something we could not reproduce.

I personally think it's one of the easier languages to learn, but then again I've been working with Java for nearly 8 years. One reason I say it's simple is that it's fairly easy to read. This does make code quite a bit more verbose though. Just make sure you start out simple. Make sure you write the obligatory Hello World application, then move on to more advanced things. There are people on the groups here that jumped right into developing against Android without knowing Java at all. That's not a great idea.

[android-beginners] Re: need help in debugging/making sense of this code
Do you know if the database had previously been created? I'm thinking
it did when you tested the notepad tutorial and therefore the
DATABASE_CREATE never gets executed. Try wiping the data on the
emulator.

hi,
I got an error on the emulator saying that the table new was not
found. From the debugger, I notice that the program never entered the
catch block, and therefore the table is not created. I borrowed this
code from the notepad tutorial and it worked fine when i did the
tutorial. Does anyone know what else I could be missing?
private static final String DATABASE_NAME = test;
private static final String DATABASE_TABLE = new;
public FileShareDbAdapter open() throws SQLException {
try {
mDb = mCtx.openDatabase(DATABASE_NAME, null);
} catch (FileNotFoundException e) { //this was never entered
even if i change the DATABASE_NAME to anything else
try {

} catch (FileNotFoundException e1) {
throw new SQLException(Could not create database);

[android-beginners] Re: Android app communicating with the outside
I don't know if the source for the android tools has been made available or will be made available, but that would be something to watch for in the future if you needed some way to write to your computers hard drive. You could also try to use the sdcard. There might be a way to mount it in your computer. That way, you could write to the sdcard from your client code, then access it in your computer. /data/data/your.app.namespace/files/out.txt is on the emulator file system. You can log in with adb shell or you can copy the file from the emulator with adb pull. So with your http post, you were using the actual ip address of your computer in the url? That should work. On Apr 1, 10:48 pm, yizhao [EMAIL PROTECTED] wrote: I can't write to the C: drive?! That sucks. Are there any other alternatives? I need the Android app to relay info to the outside world (app write data that outside programs consume). These are the two ways I came up with : ). When I said I couldn't find this file, I meant the computer file system. How do I access /data/data/your.app.namespace/files/ out.txt? Can an independent java program be able to read from this file? As for the http post, from an independent client, it works (I had to of course change 0.0.2.2 to localhost). The post hits a webapp implemented in Web Works. I have this code sitting inside the onCreate() method of an Activity. It doesn't give any on screen exceptions. Just no result on the server side. Thanks again, Yi On Apr 2, 1:24 am, Dan U.

[android-beginners] Re: android.net.http.RequestQueue - API Docs?
My guess is that if it's not documented, it's not supported and may be taken out in the next release. On Mar 29, 12:38 pm, r2d2 [EMAIL PROTECTED] wrote: Hi, I don't seem to find the API docs for the android.net.http.RequestQueue class. In fact I don't find the android.net.http package here at all: http://code.google.com/android/reference/packages.html In my code, the import android.net.http.RequestQueue does not complain. So I assume this class is a part of the API just that it's missing in the API docs.
